    Abstract: PROBLEM TO BE SOLVED: To provide an optical unit capable of regulating a magnification by providing a cut-out part to allow a wide range regulation. SOLUTION: The cut-out parts 39, 44 having respectively small cut-out parts 39a, 44a are formed respectively in a lens holding member 33 and a lens unit holding member 34, a head part 45 of a jig is inserted into the small cut-out parts 39a, 44a, to be rotated along an arrow mark direction, and the lens holding member 33 and the lens unit holding member 34 are thereby moved relatively along an optical axis L direction. The relative moving direction between the lens holding member 33 and the lens unit holding member 34 can be changed by rotating the jig counterclockwise or by rotating the jig clockwise, according to this manner.

    Abstract: An image sensor has a case, a glass cover attached to its upper surface, a head plate carrying a plurality of image sensor chips, a plurality of light-emitting elements for illuminating a document placed on the glass cover and a rod lens array for focusing the reflected light from the document on the image sensor chips, and a light-conducting member which is placed inside the case for effectively directing the light from the light-emitting elements to a specified area of the glass cover. The upper surface of the rod lens array at both its ends is compressed by compressing members formed at both end parts of the light-conducting member. The rod lens array is inserted from above into a holder having a groove formed inside the case. The holder may have protrusions formed for engaging with an edge on the upper surface of the rod lens array approximately in the middle in the longitudinal direction for easy attachment.
